BENJAMIN MALONE BISHOP, OF BLOOMINGDALE, NEW JERSEY, ASSIGNOR OF ONE-HALF TO- FRED S. WHITE,

OF BLOOMINGDALE, NEW JERSEY.

ENDLESS-BELT FEED o'R CARRYING APPARATUS.

SPECIFICATION forming part of Letters lfatent No. 700,474, dated May 20, 1902. Application filed January a; 1902. Serial No; 88,531. (No model.)

and State of New J ersey,'have invented cer-i tain new and useful Improvementsin Endless-Belt Feeder "Carrying Apparatus, of V which the following is a full and complete specification, such as will enable those skilled in the art to which it appertainsfto make and use the same.

The object of this invention is to provide an improvement in endlessbelt feed or carrying apparatus, such as is used in the manufacture of paper, in printing-presses, in machines for ironing or pressing curtains, and

for Various other purposes, whereby the endless belt, which is preferably composed of felt, but which may be composed of any suitable material, is retained at all times in proper position on the rollers on which it is placed, a further object being to provide improved means whereby the "position of the rollers may be regulated-while the machine is in motion; and with these and other objects in view the invention consistsin the construction, combination, and arrangement of parts hereinafter described and claimed.

In the drawings forming part of this specification, in which the separate parts of my improvement are designated by the same reference characters in each of the views,'Fig-' ure 1 is a side View. of my improved apparatus; 'Fig. 2, a plan viewthereof; Fig. 3,"a side View of adetail of the construction; Fig. 4, a perspective view of a part of the apparatus shown in Figs. 1 and 2, and Fig.5 a partial sectionon the line 5 5 of Fig. 4.

- the'central portion a and extending in oppo-' In the practice of my invention as shown in the drawings I providefaframe comprising a central upright portion aand two horizontal portions b and c of'less height than site directions therefrom, and these frames may be made in any desired'manner, and

- mountedin or on the top of the frame por-- tion I) isa roller 6, above which is placed another but smaller rollerf, which is supported by spring-arms g, connected with the top portion "of the central frame portion a.

Mounted on top of the central frame portion a and transversely thereof and parallel with the rollers e and f is another roller h, supported in brackets h provided at the opposite sides with set-screws M, by means of .which the bearings h may be adjusted laterally, as will be understood.

Between the rollers h and fand paralleL therewith is mounted a guide and belt-regu-J p,'and the end of ;the roller *6 opposite the bearing 11 is supported in a link j, pivotally connected with an arm j rigidly secured to one side of the upright frame portion a, and

secured to the corresponding arm g, which supports one end of the roller f by means of an upright stud j, is a springj, which is con- Y s nected with the lowerend of the link j and normally holds it in the positionshown in Figs. 1 and4. Connected with thelower end Q of the linkj by meansof-an inwardly-"direct":

ed pinj is a flexiblest'ra'pj, preferablycompassed pver'and suspendedfroin the'rolle'r h,-

posed of leather, the free end of which is adjacentto and incontactwith the'band hi." The upright portion a of the mainframe is i also provided centrally of 'theftop portion;

thereof'andabove the horizontal'frame por-.- tion 0, which is slightlyhigher tha'nth'e'hor't j p zontal frame portionb, with'twoijs'iinilar roll- 1 ers'k and k one of which is'placeddirectly 1 Y over the other, and thebearingslfi of which are supported in a bracket 70 in such manable. 3

At the front of the frame portion of and i I06 1 ported thereover and mounted -.thereon and secured thereto at the oppositesid'es thereof arevertically-arrangedsuppor ;i1t,'i-in' whicl1 v nor that theupper roller his adapted to rest a s a on thebottoin roller kzand isvertically mov-yf g are mounted two rollers m and m one of which is placed above the other, and the shafts of said rollers are free to move vertically in the bearings or supports m, and the roller m rests on the roller m and below the rollers m and m and at the end of the frame portionc of the apparatus is placed a similar roller n, between which and the upright cen tral frame portion ais a similar roller 77?, and at the opposite end of the frame portion a of and parallel with and below and at the opposite sides of the roller n are placed two smaller rollers 01 and n which are provided with slotted supports or, in which are mounted movable hearings or, which support the rollers n andwfi, and screwsn are passed through the inner ends of the supports a and connected with the bearings n, and by means thereof the position of the rollers 07. 02. may be adjusted. Suspended from the top of the frame portion 0, between the rollers n and n and at one side thereof, is a swinging hanger o, in the lower end of which is mounted one end of a roller 0 and to the right of the lower end of the hanger 0 is secured a spring 0 connected with the lower end of said hanger, and a flexible strap 0 preferably composed of leather, is also connected with the lower end of said hanger, and the free end thereof is passed over a roller 0 supported between the roller 0 and the roller 17. and below the said lastnamed roller, and said roller 0 is also provided at the end thereof with a band 0, composed of rubber or other elastic material of substantially the same thickness as the belt 19 and against which the strap 0 rests. An endless belt 12, preferably composed of felt, is mounted in this apparatus in the manner shown in the drawings, said belt being passed around the roller f, which bears on the roller 6, over the roller 71., between the rollers m and m, around and beneath the roller 01 back around the roller 01 then over the rollers o and 0 up around the roller 01", and between the rollers 7.: and 7&

The shaft of the roller m is the main powershaft of the apparatus and is driven by a pulley-wheel or other suitable device 6 (shown in Fig. 2,) and in this operation the endless belt 1) is moved in the direction of the arrows (Shown in Fig. 1.)

It will be observed that the rollers n and n are tension-rollers simply for regulating the tension of the belt, and the rollers i and o are regulating-rollers for holding the belt in proper position and for preventing the same from working laterally oif of the main guiderollers, over, around, and between which it passes. If at any time in the operation of the machine the belt 19 should move toward the linkj', which supports one end of the roller 71, the said belt would press against the straps j, which passes over and is suspended from the roller h, and the movement of the belt would operate to pull said end of the roller i upwardly and in the direction of the roller h, and this operation would cause the belt to move back in the opposite direction or toward the end of the roller '6 opposite the link j, and it will be understood that the springj after the pressure on the strap j is removed will return said end of the roller 1 back to its normal position.

The bands It and o are movable longitudinally of the rollers on which they are placed and may be moved thereon by means of the thumb and finger whenever necessary, and by this means the position of the belt may be also regulated, and said belt may be asnarrow as desired and may be operated on either side of the machine, and although I have shown two of these devices it will be understood that one or more may be employed, as desired.

It will be understood that the end of the roller 0 opposite the hanger 0 is supported in the same manner as the end of the roller i opposite the link j. In other words, the end of the roller 0 opposite the hanger 0 is provided with a swiveled support similar to that shown in Fig. 3, and said hanger operates in the same manner as the link j.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An apparatus of the class described provided with a plurality of carrying-rollers between some of which and over or around others of which an endless belt is passed, and a supplemental guide-roller over which the said belt is passed and one end of which is provided with a swiveled support and the other end of which is mounted in a swinging su pport,substantially as shown and described.
